Window Layout Resizer 作成者: Ray

This extension allows you to adjust the current window layout size to the commonly used sizes (like half, one-third, or quarter window sizes). You can define your own custom layout size from the options page or change the order of items that are shown in the popup window. The extension is compatible with high resolution (HD) (like Retina) displays and handles multiple monitors very well. Also, the layout settings work fine if a monitor is replaced (percentages are stored instead of the absolute values).

This can be used to split your screen into different sections and place different web pages into different areas.
